  • Comfortable working across the full stack — from API design to UI integration

  • Bonus: React Native (or similar) for mobile development

  • Back-end orientation with an eye for great user experiences

  • Experience in consumer, social, or event-based products is a plus

  • Self-sufficient, proactive, and motivated by meaningful work

 

Details
